B600 decode

Hi again,

Looking for a decode on this old B600 bus I found at the local scrap yard. Particularly interested in what transmission it has and what type and ratio rear axle.

Thanks!

B60 = B600 gas

C = 330 2V MD

N = Norfolk assembly plant

874343 = 1966 series number

242 = 242 inch wheelbase

No color code. Usually a bus will be chrome yellow. This is a special order, so color could have been part of it, but then it's a cowl and chassis, so not much paint involved anyway

B601 = B600 gas, 15,000lbs GVWR

84 = Cowl and chassis

O66D--this looks like the trans and axle are all together. If this is the case and it really is O66D, then:

O = Dana (Spicer) model 8055-A (or -C) five speed overdrive transmission OR New Process model 541 five speed direct transmission

66 = Timken model F106 Single Speed Rear Axle / 7.20-1 / 15,000 lbs. axle capacity.

D = Ford-Rockwell (Timken) 7,000lbs capacity.

15000 = 15,000lbs GVWR

164 3800 = 164 certified net HP @ 3800 RPM

210746
21 = Atlanta District Code
0746 = Special order number

It is probably the NP transmission as OD makes no sense in a school bus

Since it was a cowl and chassis, I'm surprised the district code wasn't 87 for body company.

Thanks for the decode. I confirmed it does in fact have the NP541.

Struck out again on the rear axle. One of these days I'll luck up and find a Rockwell H170 with the 5.86 ratio.

Went ahead and grabbed the grille and other odds and ends for wall hangers in my shop..
